This unknown option from Google Maps improves location when you lose the GPS signal

Navigation applications show their limits as soon as the GPS signal is lost. Meanwhile, But Google Maps has a little -known function which allows you to find a precise location in non -covered areas.

An arrow that turns without reason. For example, a misinterpreted crossroads or a route that suddenly disappears from the screen: in certain areas, even the best navigation application can lose the north. Meanwhile, Tunnels, underground parking lots or some large urban centers often block GPS signals. Moreover, And if your phone no longer receives this data, Google Maps becomes much less reliable.

To remedy this well -known weakness, Google has not seen all its geolocation system. Therefore, He preferred to bet on an existing device, already tested on another application: Bluetooth beacons. For example, You may have already crossed them without knowing it. this unknown option google maps However, because they are invisible, silent, and installed for several years in many tunnels from around the world thanks to the Waze Beacons project. From now on, these tags are also compatible with Google Maps, but it is still necessary to activate the function.

The principle is simple: in a tunnel. the Bluetooth tags installed in the walls send a signal detectable by your smartphone. The latter uses these benchmarks to estimate your position, with sufficient precision to avoid route errors. Unlike GPS, these tags do not need a clear sky or an internet connection. They operate with most modern smartphones, within a radius of thirty meters.

However, the option remains deactivated by default. To activate it, you have to go to Google Maps on Android, then press your profile photo (top right). Then direction Settings> this unknown option google maps Navigationthen activate the switch entitled Bluetooth tags for tunnels. During the first activation, an authorization request will be displayed to allow the application to access Bluetooth connectivity. Once this green light is given, no need to come back: Google Maps will manage the rest automatically.

This technology. already used in several large cities like Paris, New York or Sydney, is particularly useful in complex tunnels with several branches. It can also avoid expensive errors, such as taking the wrong outing or missing a crucial turn. And even if the coverage is still partial – the tags being mainly deployed in tunnels – Google could in the future extend their use to other environments such as stations. parking lots or shopping centers.

Activating this function will not radically transform your daily life on the road. but it can avoid unpleasant situations where most this unknown option google maps navigation applications abandon. This small discreet setting therefore deserves a place in the parameters of all the drivers who are anxious to keep the course. even when the GPS is silent.
